AngioSense 750EX Fluorescent Imaging Agent

false

In vivo optical imaging of vascular changes and vascular leak is an emerging modality for studying altered physiology in a variety of different cancers and inflammatory states. In oncology, increases in tumor vascular permeability can be an early indicator of tumor angiogenesis. In inflammatory disease increased vascular permeability can indicate alterations in fluid homeostasis in an acute edema response or in chronic organ conditions.

PerkinElmer’s AngioSense® NIR fluorescent probes are designed to evaluate vascular changes to better understand various disease states or provide valuable information on effects of drug candidates earlier in the development process.

For laboratory use only. This product is intended for animal research only and not for use in humans.

AngioSense 750EX NIR fluorescent imaging probe is an in vivo blood pool vascular agent that remains localized in the vasculature for extended periods of time (0-4 hrs) enabling imaging of vascularity, perfusion, and vascular permeability at a wavelength of 750 nm. The probe accumulates in tumors and arthritic joints at 24 hrs. AngioSense 680EX can be used as a single probe or multiplexed with probes at other wavelengths.

Application Note

Optical-based in vivo imaging of vascular changes and vascular leak is an emerging modality for studying altered physiology in a variety of different cancers and inflammatory states. A number of fluorescent imaging probes that circulate with the blood, but have no target selectivity, have been used to detect tumor leakiness as an indication of abnormal tumor vasculature. Inflammation is also characterized by distinct vascular changes, including vasodilation and increased vascular permeability, which are induced by the actions of various inflammatory mediators. This process is essential for facilitating access for appropriate cells, cytokines, and other factors to tissue sites in need of healing or protection from infection. This application note investigates the use of three fluorescent imaging probes, to detect and monitor vascular leak and inflammation in preclinical mouse breast cancer models.

Technical Note

AngioSense® 750 EX is a fluorescent in vivo blood pool imaging agent. AngioSense® 750 EX is a near-infrared labeled fluorescent macromolecule that remains localized in the vasculature for extended periods of time and enables imaging of blood vessels and angiogenesis.,AngioSense® 750 EX can be used to study angiogenesis, as a marker for blood vessel density, in animal tumor models. AngioSense® 750 EX can be used to characterize vascular changes and therapeutic responses associated with animal models of arthritis.
